external vibration module 130 of theelectronic device 100 receives thevibration drive signal 102, thevibration module 130 provides a corresponding vibration effect in real time with the audio (an explosion sound) at that time, and the vibration intensity and/or vibration frequency of thevibration module 130 is positively correlated with the loudness. Therefore, the vibration driving method and theelectronic device 100 of this embodiment manage to provide a vibration function with a good somatosensory experience effect. - In some embodiments, the
processor 110 executes other application programs, and when a specific event of the application program occurs, the application program outputs a message signal. Theaudio analysis module 111 determines whether to output another vibration drive signal to the built-in orexternal vibration module 130 of theelectronic device 100 according to the message signal. In an embodiment, when a power management module executed by theprocessor 110 detects that the power is low, the power management module outputs a power warning message signal, and theaudio analysis module 111 outputs another vibration drive signal to the built-in orexternal vibration module 130 of theelectronic device 100 according to the power warning message signal, so as to alert the user through a vibration effect. In an embodiment, when an e-mail management module executed by theprocessor 110 receives a new email, the e-mail management module outputs a letter alert message signal. Theaudio analysis module 111 outputs another vibration drive signal to the built-in orexternal vibration module 130 of theelectronic device 100 according to the letter alert message signal, so as to alert the user through a vibration effect. - Referring to

FIG. 4 toFIG. 6 , theelectronic device 400 performs the following steps S601 to S614 in an embodiment, to achieve a vibration effect. In step S601, theprocessor 410 outputs theaudio signal 401 to theaudio player 420. In step S602, theprocessor 410 executes theaudio analysis module 411 to analyze theaudio signal 401. In step S603, theprocessor 410 determines whether theaudio signal 401 includes a left channel signal and a right channel signal. If not, theprocessor 410 performs step S604. If so, theprocessor 410 performs step S605 and step S610. In step S604, theprocessor 410 executes theaudio analysis module 411 to determine whether theaudio signal 401 is a left channel signal. If not, theprocessor 410 performs step S610. If so, theprocessor 410 performs step S605. - In step S605, the
processor 410 executes theaudio analysis module 411 to determine whether the left channel signal has a first loudness with a first audio frequency lower than a default frequency threshold according to a first audio frequency distribution of the left channel signal. If not, theprocessor 410 performs step S602 to continuously monitor theaudio signal 401. If so, theprocessor 410 performs step S606. In step S606, theprocessor 410 executes theaudio analysis module 411 to generate the firstvibration drive signal 402 according to the first loudness. In step S607, theprocessor 410 executes theaudio analysis module 411 to define whether theexternal device 500 is located on the left side of theelectronic device 400 according to an external device setting. If so, theprocessor 410 performs step S608. If not, theprocessor 410 performs step S609. In step S608, theprocessor 410 executes theaudio analysis module 411 to output the firstvibration drive signal 402 to thethird vibrator 510 of theexternal device 500. In step S609, theprocessor 410 executes theaudio analysis module 411 to output the firstvibration drive signal 402 to thefirst vibrator 431. - In other words, when the mouse is located on the left side of the
electronic device 400, it indicates that the user's left hand is placed on the mouse. Therefore, theprocessor 410 drives thethird vibrator 510 of theexternal device 500 to enable the user to feel a vibration effect corresponding to the left channel signal. Conversely, when the mouse is located on the right side of theelectronic device 400, it indicates that the user's left hand is placed on thesecond body 400B of theelectronic device 400, in an embodiment, on the left side of the keyboard or touch panel. Therefore, theprocessor 410 drives thefirst vibrator 431 to enable the user to feel a vibration effect corresponding to the left channel signal. In addition, regarding the external device setting of this embodiment, the external device setting means that the user performs a setting operation in an operation system performed by theprocessor 410 in advance, so as to designate the use orientation of the mouse to be the left or right side of theelectronic device 400. - In step S610, the
processor 410 executes theaudio analysis module 411 to determine whether the right channel signal has a second loudness with a second audio frequency lower than the default frequency threshold according to a second audio frequency distribution of the right channel signal. If not, theprocessor 410 performs step S602 to continuously monitor theaudio signal 401. If so, theprocessor 410 performs step S611. In step S611, theprocessor 410 executes theaudio analysis module 411 to generate the secondvibration drive signal 403 according to the second loudness. In step S612, theprocessor 410 executes theaudio analysis module 411 to define whether theexternal device 500 is located on the right side of theelectronic device 400 according to the external device setting. If so, theprocessor 410 performs step S613. If not, theprocessor 410 performs step S614. In step S613, theprocessor 410 executes theaudio analysis module 411 to output the secondvibration drive signal 403 to thethird vibrator 510 of theexternal device 500. In step S614, theprocessor 410 executes theaudio analysis module 411 to output the secondvibration drive signal 403 to thesecond vibrator 432. - In other words, when the mouse is located on the right side of the
electronic device 400, it indicates that the user's right hand is placed on the mouse. Therefore, theprocessor 410 drives thethird vibrator 510 of theexternal device 500 to enable the user to feel a vibration effect corresponding to the right channel signal. Conversely, when the mouse is located on the left side of theelectronic device 400, it indicates that the user's right hand is placed on thesecond body 400B of theelectronic device 400, in an embodiment, on the right side of the keyboard or touch panel. Therefore, theprocessor 410 drives thesecond vibrator 432 to enable the user to feel a vibration effect corresponding to the right channel signal. - It should be noted that, in step S603, when the
processor 410 determines that theaudio signal 401 includes both the left channel signal and the right channel signal, theprocessor 410 performs step S605 and step S610 to respectively determine whether the left channel signal and the right channel signal have conditions to trigger a vibration effect. If so, theprocessor 410 simultaneously drives either thefirst vibrator 431 or thesecond vibrator 432 and thethird vibrator 510. If not, theprocessor 410 drives one of thefirst vibrator 431, thesecond vibrator 432, and thethird vibrator 510. Therefore, the vibration driving method and theelectronic device 400 of this embodiment provide a vibration function with a good somatosensory experience effect. - In summary, the electronic device with a vibration function and the vibration driving method of the disclosure trigger a vibration effect in real time according to a change of an audio frequency of an audio signal, and are further matched with different audio effects of a left channel and a right channel to provide the vibration effect in different positions of the electronic device. In addition, the electronic device with a vibration function and the vibration driving method of the disclosure are further matched with a setting position or usage mode of an external device with a vibrator to correspondingly adjust the position providing a vibration effect.
